Application'l'ed July 24, 1926. Seriali'No. 124,598.

The present'invention relates more.- parwashing ofthe body and chassis of an autol i mobile.

More specifically, thel pit con-struction of the present invention comprises spaced pardirection asV the side walls.

'floor of the pit.

alleloppositely disposed side walls, theinner surface of each wall projectingfbelow thenormal floor level and terminatingin Ythe interposed between said walls are spaced runways provided' with curbs and yextending in the same parallel The automobile washing devicesare preferably mounted on the side wall, the latter also 'functioning as a splash wall. 'The inside surfaces of the side walls may be provided'with inwardly cutaway portions functioning to receive and lpartially conceal flood lights.

Y partly in section, the section. being taken on line 1 1 of Fig. 2. `Fig. 2 is a cross-sec-y tional view taken on line 2 2 of F ig. 1

Referring morein detail to the drawings,

vl designates two spaced oppositely disposed parallelside walls which project -above the normal level .2 of the iioor immediately adjacent thereto. The inside surfaces of the walls'l project'below the, normal oor level 2, as shown at 3, terminating in the floor of the pit, shown at 4. The floor of the pit has been dropped a considerable distance below l the normal floor level, for instance, .between sixteen and twenty-four inches. The pit floor preferably slopes downwardly toward the center from each side wall, as shown at i 5, for the purpose of directing the sewage toward an outlet drain, as will be hereinafter explained. A.

Interposed between the side walls l and extending in the same parallel direction relative. to the side walls are a pair of spaced runways or piers 6, provided on their upper surface with upwardly projecting curbs?, 7.

The curbs on the runways'perf The upper surface of each pier1` 6 is preferably in substantially .the same horizontal assure plane as the normal floor level 2, in order that the car to be cleaned may be'moved from the floor von tothe runways and rolled from vthe runway to the floor with aininimum of effort.l y

As a feature of the invention, the base of eachv runway Gris providedwith apertures 8` 8, functioning as outlets, to permit the. cleaning materials, dirt, grease and the like,

toflow inwardly along the sloping floor 5 of the pit and to be collected in the catchbasin. 49 and directed to sewage through the outlet drain 10.

caf

The inside surfaces of each wall may be provided with the*` inwardly cut-away portions ll, functioning as sockets for receiving and 'partially concealing flood lights. p .It will be apparent that the pit construc- 'tion of the present invention has been carefully designed to efficiently clean and wash all outside'parts of an automobile, including the'chassis.' Bydropping the floor of the pit, the lchassis is brought on substan-n tially a direct line of vision with the work- Dien.

formed with the same efficiency as can be obtained `with natural light.

The pit is designedto accommodate two By affording facilities for a flood? light system, the night work can be perto ten workmen, according to the number of I cleaning mechanisms, and permits the cars to be easily moved backward and forward over the pit without the necessity of a person driving or guiding,l the car.

In use and operation, the pit construction ,i I

of the presentinvention functions Very etiiciently, permitting economy in labor andi' excellent results.

The entire construction isv adapted to be constructed of concrete; butit is understood I claim as my invention l. A vehicle washing pit comprising spaced opposite walls projecting above the normal floor level, spaced vehicle runways parallel with and interposed between said walls, the upper surfaces of the runways lthat other materials may be employed. l

2. A vehicle" washing pit -comprising spaced oipositewalls projecting1 above the normal oor level, spaced vehic e runways parallel with and interposed between said walls, the'upper surfaces of the runways 4lying in substantially the same plane as. the normal level of the floor immediatel adjacent'thereto, alcurb on the upper e ge of each runway, the insidesurface of each wall projecting below the normal floor lever and terminating in the pit ioo'r, the' it floor sloping downwardly from eachwal toward the center to direct the materials'to' be drained through apertures in the'base ofthe runways communicating with an outlet drain.
